SPECIFICATION forming part of4 Letters Patent No. 272,285, datedFebruary 13, 1883.

Application tiled December '22, 1882. (No model.) A

Be it known that I, EUGENE B. MAGNUS, a citizen ot the United States,and a resident of Brooklyn, in the county of Kings and State ot' NewYolk, haveinvented acertain new and use- 1 ful Automatic DuplexOar-Coupling, of which th'e following is a specication.

My invention relates to a duplex car-coupling which may be used inconnection with either freight or passenger cars, of which a fulldescription willbe given hereinafter.

Heretot'ore passenger and freight-'cars were provided With a singlecoupling at their ends, with buffers connected therewith. The singlecouplings are objectionable, from the fact that when a loadedfreight-car' is connected with that of van empty one the latter'in thiscase stands much higher than the former. Consequently a different sizelink must be used be'- tween the couplings in order to overcome thedifficulty caused thereby. The'second objection is, that should thecoupling break, which is an every-day occurrence, the cars which havebeen separated from the train are left standing and disabled, and inVmany cases are telescoped by anv approaching train from the rear. Nomeans having been provided to prevent this, it must be naturallypresumed that a serious calamity will in many cases follow.

The objections as herein stated are obviated by my duplex coupling,whichconsists of a coupling-bar having its fulcrnm beneath the bed ofthe car,near the end. The end of said bar is provided with an eye for holding` aretractin g-sprin g. rEhe said bar is provided with a curved openingnear'its foremost end for the reception of a coupling-pin.

My invention further consists of a brace having two extensions bolted tothe bottom of the car, near the end, and a main extension bolted to across-piece, which is usually employed in the construction of cars. Thesaid In the drawings, Figure l represents an inverted plan of the duplexcoupling in the opening, B and B', near their foremost ends.

O and O are their fulcrnms. D and Dl are the retracting-springs, eachhaving one of their ends connected with the eyes E and E'. Their otherends are held by the fastenings F and F. G and G are the braces,witharms H H and H' H. I and l are the main arms, bolted to the crosspiecesK and K of the cars L and L. M and M are the brace-pins with which thecoupling-bars engage when in action.

In Fig. 2 the coupling-bar ot' one car and vcouplingbarsAt and A strikeagainst their respective brace-pins M and M', causing said bars to bepushed to one side untilthe openings B and B reach the said brace-pins,at .which time the retracting-springs D and D pull the said bars hack totheirformer position, which causes the curved openings B and B' toencircle the brace-pins M and M', thereby locking them, which completesthe operation.

It will be observed that Whenever one of the pins or'arms should breakor become otherwise disabled the second contrivance is prepared toperform the function of both, thus decreasing the liability of seriousaccidents, which frequently occur with the single coupling's.

It will further be observed that my duplex coupling may be used inconnection with or without buffers.

Having thus described my invention, what I I Signed at New York, in thecounty of New 1o chiim as new, and desire to secure by Letters York andState of New York, this 21st; day of Patent, is- December, A. D. 1882.
